Organosilica materials and uses thereof

Abstract

Organosilica materials, which are a polymer of at least one independent monomer of Formula [Z¹OZ²SiCH₂]₃ (I), wherein each Z¹ represents a hydrogen atom, a C₁-C₄ alkyl group or a bond to a silicon atom of another monomer and each Z² represents a hydroxyl group, a C₁-C₄ alkoxy group, a C₁-C₆ alkyl group or an oxygen atom bonded to a silicon atom of another monomer and at least one other monomer are provided herein. Processes of using the organosilica materials, e.g., gas separation, etc., are also provided herein.

AI Technical Summary

Benefits of technology

[0009]It has been found that an organosilica material with desirable pore diameter, pore volume, and surface area can be achieved. Further, such organosilica material can be successfully prepared without the need for a structure directing agent, a porogen or surfactant.

Problems solved by technology

However, the use of a structure directing agent, such as a surfactant, in the preparation of an organosilica material, such as a PMO, requires a complicated, energy intensive process to eliminate the structure directing agent at the end of the preparation process.

This limits the ability to scale-up the process for industrial applications.
